Description:A typical inverse optimization problem is then posed as follows [Ahuja et al. the 1- or ∞-norm, is used in (1.4a), see [Ahuja et al. 2001]. The Chapter 5 Inverse Optimization Modeling of PWA Systems the affine functions ¯ψ and ¯φ satisfy the strict inequalities. ¯ψ(x,u) < max j∈N nyr. A
